　　摘 要：无人机测流系统是将雷达波流速仪集成在无人机上的一种非接触式河道流量测验方法。针对铜仁水文监测工作在遇超标准大洪水或恶劣环境下水文应急监测手段单一、数据精准度不高的问题，采用无人机测流系统在铜仁市茅溪水文站与水文缆道流速仪法进行 22 次实测数据对比试验，分析无人机测流系统实测的水面流速及流量测验误差。结果表明：无人机测流系统在水面流速超过 0.50 m/s、运行高度在 10～30 m、风力小于 7 级时，测流数据的合格率达到相关要求。无人机测流系统在贵州省铜仁市山区性河流应急监测时适应性良好，可作为铜仁水文应急监测一种安全便捷有效的方法进行推广。

　　Abstract：Drone flow measurement system is a non-contact river flow measurement method which integrates the radar wave current meter on the drone. In view of the problems that the hydrological emergency monitoring method is rare and the data accuracy is not high in Tongren, this paper applies the drone flow measurement system to conduct 22 comparative tests of measured data at Maoxi Hydrologic Station in Tongren City. The data is compared with data measured by hydrological cableway current meter method, to analyze the measured water surface velocity and flow measurement errors of the drone flow measurement system. The results show that the qualified rate of the drone flow measurement system meets the requirements of relevant phases when the water surface velocity exceeds 0.50 m/s, the operating height is 10～30 m, and the wind power is less than Level 7. The drone flow measurement system has good adaptability in the emergency monitoring of mountainous rivers in Tongren City, and can be promoted as a safe, convenient and effective method for Tongren hydrologic emergency monitoring.
